EU Antitrust Procedure: Investigation, Enforcement, and Sanctions

Introduction

EU antitrust procedure governs the European Commission’s exercise of its enforcement powers under Articles 101 and 102 TFEU. Regulation 1/2003, the procedural cornerstone of modern EU competition law, decentralised enforcement by empowering national competition authorities (NCAs) and courts to apply Articles 101–102 in full, while preserving the Commission’s central role as guardian of the internal market. The procedural framework balances investigative effectiveness with the rights of defence, subject to Charter of Fundamental Rights guarantees and CJEU supervision.

Commission Investigation Powers

The Commission enjoys broad investigatory powers under Articles 17–22 of Regulation 1/2003. Dawn raids under Article 20 empower officials, assisted by Member State competition authorities, to enter any premises, land, or means of transport of undertakings, examine books and business records, take or obtain copies, seal premises and records, and ask for oral explanations. The Commission must act within the scope of its authorisation decision and cannot conduct general fishing expeditions. The Nexans (2014) and Deutsche Bahn (2013) judgments confirmed that the Commission must delimitate the subject matter and purpose of the inspection, enabling companies to limit their cooperation obligations.

Article 21 permits inspections of non-business premises, including homes, where a reasonable suspicion exists that business records are kept there. This intrusive power requires prior judicial authorisation from the national court of the Member State concerned, although the CJEU held in Roquette Frères (2002) that the national court may not question the necessity of the inspection — its review is limited to verifying authenticity and absence of arbitrariness.

Requests for Information under Article 18 enable the Commission to require undertakings to provide all necessary information. The Commission may impose periodic penalty payments for incomplete or incorrect information. In Xinyi PV Products (2014), the General Court confirmed that the Commission cannot compel an undertaking to admit infringements under Article 18, as this would infringe the privilege against self-incrimination, though it may require factual information.

Statements of Objections and Rights of Defence

Where the Commission provisionally concludes that an infringement has occurred, it issues a Statement of Objections (SO) , a formal written document setting out the factual allegations, legal characterisation, and supporting evidence. The SO must enable the addressee to understand the case against it and exercise its right to be heard. Access to the Commission’s file — granted via CD/DVD or secure digital platform — includes inculpatory and exculpatory evidence. In Intel v Commission (2017), the CJEU annulled in part the Commission’s decision for failing to adequately engage with Intel’s efficiency arguments, affirming the Commission’s obligation to consider exculpatory evidence diligently.

The hearing before the Hearing Officer, an independent procedural officer within DG COMP, ensures that oral submissions supplement the written procedure. The Hearing Officer decides on disputes concerning access to file, confidentiality, and time limits, and reports to the Commissioner on the fairness of proceedings. The Oral Hearing is not a trial but an administrative procedure; parties respond to questions from the Commission and Member State representatives.

Leniency Programme

The Commission’s Leniency Programme (2006 Notice) offers immunity from fines or reduction of fines to undertakings that cooperate in detecting and prosecuting secret cartels. Type 1 immunity (automatic immunity) is available to the first undertaking to provide information enabling the Commission to carry out a targeted inspection or find an infringement. The marker system allows a prospective applicant to secure its place in the queue while gathering evidence. Type 2–3 reductions (30–50% for first collaborator after immunity, 20–30% for second, up to 20% for others) reward cooperation that provides significant added value.

The programme’s effectiveness depends on the interplay with private damages actions. Directive 2014/104 limits the disclosure of leniency corporate statements in national damages proceedings to protect the programme’s attractiveness, while the Pfleiderer (2011) and Donau Chemie (2013) judgments balance leniency protection with victims’ right to compensation.

Settlement Procedure

The settlement procedure (2008 Notice on settlement, codified in Regulation 773/2004) streamlines cartel enforcement where parties admit participation and liability. In exchange for a 10% fine reduction, the undertaking waives its right to an oral hearing and full access to the file, enabling the Commission to adopt a simplified decision. The settlement is not a plea bargain: the Commission retains discretion not to settle, and the undertaking may withdraw until the final settlement submission. Settlement decisions are adopted through a truncated SO procedure, reducing administrative burden and enabling faster disposition of resources.

Fines and Sanctions

Article 23 of Regulation 1/2003 empowers the Commission to impose fines up to 10% of total worldwide turnover. The 2006 Fining Guidelines establish a two-step methodology: (a) determination of the basic amount, calculated as a proportion of the value of sales (up to 30% depending on gravity), multiplied by the number of years of infringement, plus an entry fee of 15–25% for cartels; and (b) adjustment for aggravating circumstances (recidivism, leadership role, obstruction) or mitigating circumstances (negligence, termination, effective cooperation beyond leniency).

The 10% turnover cap is a ceiling, not a target; the Commission enjoys a margin of appreciation within the cap, subject to proportionality review. In Pioneer (2018, upheld 2020), the General Court confirmed the Commission’s approach of calculating the basic amount on the last full year of the infringement, though this methodology is subject to ongoing debate. The Recidivism enhancement allows the Commission to multiply the basic amount by up to two for repeat offenders within the same or related market.

Commitments

Article 9 of Regulation 1/2003 permits the Commission to adopt a decision making commitments binding on undertakings without concluding an infringement. Commitments decisions — increasingly common in Article 102 cases (Google Shopping, Amazon Marketplace) — offer efficiency gains but lack the deterrence of infringement decisions and do not establish a violation for follow-on damages claims. The Alrosa (2010) judgment confirmed that commitments may go beyond what the Commission could impose by decision, provided they are proportionate.
